Christian Martineau and Christine Gagnon are among the first graduates in the world in synergology. Their work leads them to give lectures and training in several sectors of activity, among others in the prison environment, the armed forces and security.
“I bought this book to deepen my knowledge of synergology since it was my next topic at Toastmasters International. I loved this book, I read one page after another and it so fast that I wanted more once at the end of the book. A lot of stuff for exactly “Seeing Lying”. Ideal for detectives, military, police interrogations, negotiations and even for parents of teens. ”
